一、非限制性定语从句的用法
非限制性定语从句与先行词的关系并不十分密切,只是对主句的内容或先行词进行补充、解释或附加说明,缺少也不会影响对全句的理解。它与主句或先行词之间一般用逗号隔开,常常单独翻译,没有它,主句意思仍然完整。引导非限制性定语从句的关系代词和关系副词在非限制性定语从句中不能省略。
The sun,which rises in the east,gives us heat and light.太阳从东方升起,带给我们光和热。
This is our headmaster,who I think has something crucial to tell you.这是我们的校长,我认为他有非常重要的事情要告诉你。
